Four Strategic Pillars of Our Quality System
Our quality management architecture guarantees that every piece of steel delivered adheres to rigorous international benchmarks through structured control points.
Raw Material Control
All incoming materials are vetted via chemical spectrometry and mechanical checks against approved mill test certificates before inventory entry.
In-Process Quality (IPQC)
Continuous dimensional, ovality, and visual surveillance during cutting, forming, machining, and beveling ensures any deformity is promptly rejected.
Advanced Laboratory Testing
Cutting-edge in-house and accredited lab facilities conducting mechanical, non-destructive (NDT), and corrosion tests per customer QAP.
Complete Traceability
Unbroken records preserved at all steps. Unique heat numbers, material grades, and size codes stamped on each component with complete documentation.
Comprehensive Testing & Inspection Matrix
Katariya Steel Distributors ensures all products comply with ASTM, ASME, DIN, EN, ISO, and client-specific datasheets through an extensive array of destructive and non-destructive evaluations.
Mechanical & Physical Testing
Verifying structural strength, ductility, and elasticity
-
Tensile & Yield Testing: Measurement of ultimate tensile strength, yield point, and elongation percentage.
-
Charpy V-Notch Impact Test: Impact energy absorption testing at ambient and sub-zero temperatures (down to -196°C).
-
Hardness Testing: Standardized Rockwell (HRC/HRB), Brinell (HBW), and Vickers (HV) hardness verification.
-
Deformation Tests: Flattening, flaring, bend, and expansion tests for pipes, tubes, and fittings.
-
Proof Load & Wedge Testing: High-tensile fastener testing to ensure clamping performance under load.
Chemical & Metallurgical Analysis
Verifying chemical composition, microstructure, and alloy integrity
-
Positive Material Identification (PMI): High-precision handheld XRF & OES spectrometers for instant grade confirmation.
-
Spectrographic Chemical Analysis: Full elemental breakdown including Carbon, Chromium, Nickel, Moly, and trace elements.
-
Intergranular Corrosion (IGC) Testing: ASTM A262 Practices A, B, C, and E for stainless and duplex alloys.
-
Microstructure & Grain Size: Metallurgical micro-examination, inclusion rating, and phase balance (Ferrite/Austenite ratio).
-
Pitting & Crevice Corrosion: ASTM G48 Method A/B ferric chloride corrosion resistance testing.
Non-Destructive Testing (NDT)
Sub-surface flaw detection without altering product integrity
-
Ultrasonic Testing (UT): Detecting internal laminations, inclusions, and discontinuities in plates, forgings, and welds.
-
Hydrostatic Pressure Testing: Pressure holding integrity testing up to 10,000 PSI to verify zero leakage.
-
Radiographic Testing (RT): X-ray and Gamma-ray examination of welded pipes, fittings, and heavy wall components.
-
Magnetic Particle Testing (MPI): Detection of ferromagnetic surface and near-surface cracks and seams.
-
Liquid Penetrant Inspection (DPI/PT): Fluorescent and dye penetrant testing for non-porous material surface defects.
Dimensional & Surface Inspection
Precision calibration and 100% aesthetic defect scanning
-
Digital Caliper & Micrometer Gauging: Precise verification of Outer Diameter (OD), Inner Diameter (ID), and lengths.
-
Ultrasonic Wall Thickness Gauging: Continuous thickness mapping across pipe bodies and fitting bends.
-
Flange Facing & Serration Check: Surface roughness (Ra value) verification per ASME B16.5 / B16.47 specifications.
-
Bevel End & Root Face Inspection: Angle verification (37.5° ± 2.5°) and root face checks for seamless site welding.
-
100% Surface Visual Inspection: Zero tolerance for pit marks, gouges, dents, scratches, or scale formations.
5-Stage Systematic Quality Process
From raw material inwarding to international seaworthy dispatch, each batch advances through sequential verification checkpoints.
Inward Raw Material Audit
